I really don't get all the negative critics here. I don't know the team, but looking objective at the game I am very impressed!
The kits are nicely balanced, they all have an innovative tool to play with and they all work great tactically together. It is not as tactical as Battlefield and not as fast paced as Quake but - though these games are odd to compare - I find it a happy medium. And while all the weapons got a great, smooth feeling, you get a smile on your lips, when pulling the trigger.
The graphics are nearly the best part of the game - all the maps got their own look and atmospheric colours and settings. The textures and models are unique to each level and they got plenty of details.
Sadly it isn't very well optimized, so my fps falls from about 60 to 15 at some parts of the game, and we all know that the Source engine isn't the most requiring one (any longer). So that part needs some work...
Still the game runs acceptable at a bit lower settings and I enjoy playing it. But here comes the greatest problem - most of the time there aren't any servers! So I have only been able to play an online match a single time and that was a laggy experience. Apart from that I've only been playing LAN matches. I will go as far as to say that this is my overall favourite mod and it is hard for me to understand why no one is playing it and why the developers don't start at least one stable server! If they did so I would be the first to visit it - especially if I wasn't the only one.
